Enum RelLength 

#[non_exhaustive]
pub enum RelLength {
    Single,
    Variable {
        min: Option<u64>,
        max: Option<u64>,
    },
}

Variable-length relationship bounds. Single means no * qualifier. Spec §5.3.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Single

Exactly one hop (-[r]->).

Variable

Variable number of hops (-[r*min..max]->). Bounds of None mean unbounded in that direction.

Fields

min: Option<u64>

Lower bound on the number of hops; None means no lower bound.

max: Option<u64>

Upper bound on the number of hops; None means no upper bound.

Trait Implementations

impl Clone for RelLength

fn clone(&self) -> RelLength

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RelLength

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RelLength

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Hash for RelLength

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RelLength

fn eq(&self, other: &RelLength) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RelLength

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for RelLength

impl StructuralPartialEq for RelLength
